Notwithstanding that Motorola has designed (and qualified) the PTP 250
products to generally meet the Class B requirement to minimize the
potential for interference, the PTP 250 product ranges are not marketed for
use in a residential environment.
Radio and television interference
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
• Reorient or relocate the Outdoor Unit (ODU).
• Increase the separation between the affected equipment and ODU.
• Connect the ODU and PoE power supply into a power outlet on a circuit different
from that to which the receiver is connected.
• Consult your installer or supplier for help.
Maximum permitted EIRP
In most countries, operation of products in the band 5470 MHz to 5725 MHz is
constrained by an EIRP limit. The constraint is that the EIRP must not exceed 30 dBm
or (17 + 10 x Log Channel width) dBm.
In some countries, operation of products in the band 5725 MHz to 5875 MHz is
constrained by an EIRP limit. The constraint is that the EIRP must not exceed 36 dBm
or (23 + 10 x Log Channel width) dBm.
For examples of countries that impose an EIRP limit, refer to Table 4-23.
